It came as a big suprise to me but most US units don't carry the latest FLIR/Wescam kit, the new generation stuff is much heavier and if you have a look inside both US and European Police aircraft the kit is mounted in a much more substantial way. The US all tend to use Police officers as Pilots and cut the crew to two. Like most UK units we fly at nearly max weight. We have cut our kit to as low as it will go. Believe me there's enough work for two officers and no way could one officer/observer do more than do a missing person search. Anything more you need two observers.
